Light of frequency two times the threshold frequency is incident on photosensitive material. If the incident frequency is made and intensity is doubled, then the photoelectric current will
Options:
Answer:
C
Solution:
Initial frequency Final frequency is less than the threshold frequency Hence no photoelectrons will be emitted, and photoelectric current will be zero.
